The Washington State Department of Agriculture (WSDA) announced it has detected residues of one or more undisclosed pesticide ingredients in 15 products. Several of these products contain ingredients that are not allowed for use on marijuana, which could cause marijuana to fail the Washington State Department of Health pesticide testing requirements for compliant marijuana products.
“In addition,” reads a joint official announcement from the WSDA and the Washington State Liquor and Cannabis Board (WSLCB), “some of these ingredients could result in the Washington State Liquor and Cannabis Board confiscating and destroying marijuana if they are found on products in quantities above the recently adopted action levels.”
“The WSDA has issued statewide stop sale orders for these products, and these products are not allowed for use on marijuana in Washington until further notice,” the announcement reads.
